Zinc Oxide (ZnO) thin film has been synthesized using the chemical spray pyrolysis technique and ethylene glycol has been used as solvent during the synthesis. X-ray diffraction (XRD) results show cubic and tetragonal phases of ZnO and the grain size was calculated to be 2.57nm. Optical characterization reveals very high transmittance within the visible-ultraviolet region and a bandgap of 3.49 eV was obtained for ZnO thin film. Scanning Electron Microscopic (SEM) analysis showed a void-free non-homogenous surface.
